* revert r105521, which is breaking the buildbots with stuff like this:Chris Lattner2010-06-051-197/+19

| | | | llvm-svn: 96031
* fixme resolved!Chris Lattner2010-02-121-1/+0

| | | | llvm-svn: 96028
* add a bunch of mod/rm encoding types for fixed mod/rm bytes.Chris Lattner2010-02-121-0/+20
| | | | | | | This will work better for the disassembler for modeling things like lfence/monitor/vmcall etc. llvm-svn: 95960
* fix the encodings of monitor and mwait, which were completelyChris Lattner2010-02-121-7/+2
| | | | | | | busted in both encoders. I'm not bothering to fix it in the old one at this point. llvm-svn: 95947
* add a new MCInstPrinter::getOpcodeName interface, when it is Chris Lattner2010-02-111-4/+4
| | | | | | | implemented, llvm-mc --show-inst now uses it to print the instruction opcode as well as the number. llvm-svn: 95929
* make getFixupKindInfo return a const reference, allowingChris Lattner2010-02-111-4/+7
| | | | | | | the tables to be const. Teach MCCodeEmitter to handle the target-indep kinds so that we don't crash on them. llvm-svn: 95924
* switch to target-indep fixups for 1/2/4/8 byte data.Chris Lattner2010-02-111-14/+9
| | | | llvm-svn: 95920
* refactor the conditional jump instructions in the .td file toChris Lattner2010-02-111-0/+2
| | | | | | | use a multipattern that generates both the 1-byte and 4-byte versions from the same defm llvm-svn: 95901
* dont' call getX86RegNum on X86::RIP, it doesn't like that. ThisChris Lattner2010-02-111-2/+4
| | | | | | fixes the remaining x86-64 jit failures afaik. llvm-svn: 95867
* fix a really nasty bug I introduced in r95693: r12 (and r12d, Chris Lattner2010-02-111-4/+6
| | | | | | | | | r12b, etc) also encodes to a R/M value of 4, which is just as illegal as ESP/RSP for the non-sib version an address. This fixes x86-64 jit miscompilations of a bunch of programs. llvm-svn: 95866
* Add and commonize encoder support for all immediates.Chris Lattner2010-02-111-110/+35
| | | | | | | | | | | | | | | Stub out some dummy fixups to make things work. We can now emit fixups like this: subl $20, %esp ## encoding: [0x83,0xec,A] ## fixup A - offset: 2, value: 20, kind: fixup_1byte_imm Emitting $20 as a single-byte fixup to be later resolved by the assembler is ridiculous of course (vs just emitting the byte) but this is a failure of the matcher, which should be producing an imm of 20, not an MCExpr of 20. llvm-svn: 95860
* generalize EmitDisplacementField to work with any sizeChris Lattner2010-02-111-14/+13
| | | | | | and rename it to EmitImmediate. llvm-svn: 95859
* eliminate the dead IsPCRel argument.Chris Lattner2010-02-111-9/+6
| | | | llvm-svn: 95858
* eliminate the dead "PCAdj" logic.Chris Lattner2010-02-111-22/+9
| | | | llvm-svn: 95857
* emit some simple (and probably incorrect) fixups for symbolicChris Lattner2010-02-101-34/+32
| | | | | | displacement values. llvm-svn: 95773
* keep track of what the current byte being emitted isChris Lattner2010-02-101-74/+87
| | | | | | throughout the X86 encoder. llvm-svn: 95771
* simplify displacement handling, emit displacements by-operandChris Lattner2010-02-101-50/+19
| | | | | | even for the immediate case. No functionality change. llvm-svn: 95770
